How Do I Force A Hard Drive to Format to FAT32

I was trying to format my old hard drive to FAT32, but the option is greyed out in Disk Management. Then, I tried File Explorer, but the problem still remains. How do I force a hard drive to format to FAT32? Appreciate any answers.

To force a hard drive to format to FAT32, you'll have to use a third-party tool. 

Since Windows limits users from formatting a hard drive larger than 32GB to FAT32, you might notice the format option greyed out in Disk Management. Thus, a professional drive formatter is the only easy and safe way to do it.

EaseUS Partition Master Free offers the features you need. One recommended point is that its "NTFS to FAT" feature even allows you to complete the entire formatting process without losing data on the disk.

If you are not planning to lose the data on your hard drive, follow the steps here to format your drive:

For those users whose disks are not NTFS-formatted, you can directly right-click on the target partition, select "Format", and then choose to format it as FAT32.
